Just letting you know,
Checking coil resistance alone can tell you if you have the correct coil, but no guarantee that it's a good coil without other tests (ie. hypot test). Coils often fail under load only. When winding insulation begins breaking down, internal shorts only happen at the higher working voltages, and not the low voltages of a typical ohm meter (1.5 volts).
Doesn't sound like a battery to me. Usually when cells short out in a battery it's not intermittent like that. Sounds like possibly something in the wiring is intermittently shorting to ground or a component is shorting to ground. Possibly only a partial short. Could also be an open. Try turning on the ignition and banging around the car, or pulling on the wiring harness in various places to see if you can find the area. Looking at my schematic these two items share wiring from fuse box-1 at the power side of fuses 7, and 8, (they're tied together here and get power from the ignition switch), back thru a 6 terminal connector to the ignition switch then thru another 6 terminal connector to the battery. These two parts get power from this tie point at the fuse box from the ignition switch directly, and from here it splits off to each unit. It doesn't look like these two items have fuses on your car. I could email you scanned copies of the schematic if you want, (2 sheets).
